Anyone have any experience with either? I've seen the spyder around a lot, I'm really curious about Pantone's product, especially since it mentions adjusting for ambient. That feature isn't available in the Spyder until about $190 more.

I have the Spyder2 and it is easy to use and it seems to work well. I calibrated a laptop and desktop and images appeared very consistent across those machines. Also have soft proofed using profiles for labs and the prints were right on. Soft proofing for my r2400 with custom profiles is also very close. It is important to note that I always edit in a darkened room.

Just ordered the upgrade to the pro version so I must be happy with it.

We ended up purchasing the GretagMacbeth Eye-One Display 2. I calibrated three monitors so far with it, and they seem consistent. The ambient-light measurement feature is pretty handy. It doesn't affect the monitor calibration, but lets you know the temperature and intensity of your ambient light. Too warm or cool ambient light will affect how the colors look on the screen. They also don't recommend working in the dark because it strains the eyes. Hope this helps!
